As you might be aware, there's been some amount of debate in the browser community recently about the use of vendor prefixes in the web platform. I'm sure many of you have opinions on this topic, but rather than triggering a long thread about this topic, I'd like to start by gathering some data about WebKit's current use of vendor prefixes. I've put together a list of all the vendor-prefixed APIs I could find in WebKit, at least for DOM interfaces: https://trac.webkit.org/wiki/PrefixedAPIs I'd like to try to understand the current status of these APIs on the standards track. If you happen to know which specifications contain these various APIs (and the standardization status of these specifications), would you be so kind as to add a link from the wiki to the specification? If there isn't a specification, please feel encouraged to note that on the wiki together with any information you're aware of about future plans for writing a specification. I'll do my best to fill in the gaps in a few days. Many thanks, Adam P.S., If you'd be willing to fill in the list of vendor-prefixed CSS properties, I'd appreciate that as well.
